2x2 Video Wall Controller for Four Displays

This LUOM controller splits a single HDMI or DVI source across four HDMI screens in a 2x2 grid. It suits installers building digital signage, control-room walls or retail displays that need one large image from a single player.

HDMI 1.4 Input Limits Output to 1080p

The unit accepts 4K at 30 Hz or 1080p at up to 60 Hz but every output is fixed at 1920x1080p. HDCP 1.4 compliance protects standard protected content but newer HDCP 2.2 streams will not pass through. Audio can be taken from a 3.5 mm jack as 2.0 CH or from optical SPDIF as 5.1 CH.

Plug-and-Play Setup with Remote and 180° Rotation

Power the box from the included 5V 2.1A adapter, connect source and screens, then select one of eight display modes via the remote. The 180° rotation works only in 2x2 mode; other layouts do not support it. No drivers or software are required.

Questions about this item

Should I pick the 2x2 mode or one of the 1x4 or 4x1 layouts for my four screens?

Choose 2x2 for a square video wall, 1x4 for a horizontal ribbon, or 4x1 for a vertical column — all four HDMI outputs are active in every mode.

The box says 4K 30Hz input but 1080p output — what resolution will I actually see on each monitor?

Each of the four displays receives a 1920x1080 60Hz signal; the 4K 30Hz source is down-scaled and split into four quadrants.

Does the HDMI 1.4 input limit the refresh rate or colour depth at 4K?

HDMI 1.4 caps the input at 4K 30Hz 4:4:4 or 4K 60Hz 4:2:0; the controller outputs 1080p at 60Hz regardless.
